The prominent, large equivalent width Fe K-alpha, Fe K-beta, and Ni K-betafluorescent emission lines in the X-ray spectrum of IGRJ16138-4848 represent analmost unique laboratory to study the conditions of the accretion flows inbinary systems. There is evidence for changes of the quantities defining theaccretion flow on different timescales, possibly related to the overall X-rayoutput. We propose a monitoring campaign of IGRJ16138-4848 during the XMM-NewtonAO3, in order to study the relation between the X-ray output and the physicalstate of the accreting matter, and the evolution of the accretion flow geometry,distribution and covering factor. We request 4 observations, covering timescalesfrom days to months, for a total allocation time of 80 ks.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
